COATINGSPRO JULY 2018 19 tried-and-true product technology that is known generically as a "Peel & Stick " type membrane. In today's new chemi- cal wall world, the oils in the asphalt can migrate into an air barrier of a different chemical composition, again causing premature degradation and subsequent failures. e tried-and-true legacy material may not work with the new flashing. e same holds true with the roof-to-wall transition membrane. If different chemical products are specified or used, then mutual letters of compatibility should be acquired from both manufacturers. Another pathway through the chemical issue with through-wall flashing is the use of copper or stainless steel flashing products as these types of materials are chemically inert and compatible with all air barriers, insulations, and sealants. Copper or stainless steel are costlier, but they are the same installed cost and, in many instances, less on an installed cost basis and come with a significantly longer warranty. What Can You Do? First, use your resources from indus- try-recognized associations, such as the Air Barrier Association of America (ABA A). Check for the Certified Air Barrier Contractors in the geographical job location, and list that qualification in your specifications for Contractor Qualifications. Research and choose the Evaluated ABA A Assembly that best suits your design criteria from the ABA A website. List those product technologies in the Acceptable Materials section of your specification. For other issues pertaining to compliance, you' ll need to go to the manufacturer's websites to obtain those statements. You' ll need to get letters from both the insulation and the air barrier manufacturers attesting to the fact that they are NFPA-285 compli- ant together, regarding that topic. Using legacy specs can be helpful and harmful. Be sure to pay attention to the ever-evolving landscape, and review your materials carefully.
